Cavalier vs. Pug
If you were choosing between a pug and a Cavalier King Charles Spaniel, I'd say Cavalier in a heartbeat.
Pugs are CERTAINLY not low-maintenance. They require the creases in their face to be cleaned at least weekly, more often the better. Also, as pugs get older, they often require eye drops every other day or so. Pugs don't do well in very hot weather OR very cold weather because of their short noses, so if you have really hot summers and really cold winters, they aren't the best choice. They are also heavy seasonal heavy shedders, but shed year-round too. Aside from that, pugs are truly WONDERFUL little dogs, I have nothing against them, they are extremely sweet (maybe even one of the most affectionate small breeds in general). But honestly, I couldn't handle all of the work their face requires and all of their health problems..
I LOVE cavaliers in the first place, so excuse me if I sound just a bit biased
. They have fantastic temperments and are truly big dogs in a small package. They have the temperment of a tiny golden retriever. They LOVE getting as much daily excersize as possible but are very adaptable and can deal with a long walk or 2 or 3 short walks around the block daily. They love swimming and retrieving (they are spaniels!). They are great with kids, an average shedder, and are small enough to travel just about anywhere. The reason I DON'T have one this second is because of the health epidemic with their breed. Matral valve desease (MVD) is notorious in the breed. 50% of cavaliers have it by the time they are 5 years old and 100% have it by the time they are 10 years old, therefore giving the breed a much shorter liespan than most other smaller breeds. Now, they can go years without any symptoms, even after being diagnosed. But once they start showing symptoms, then it is something to worry about and you will need medication. If you excersize it alot then it can live a longer life, I know someone who had a cavalier (who was the sweetest dog ever!) who walked him at least a mile EVERY day, and he didn't have symptoms until he was fifteen. Of course, not everyone can do this, so MVD is a big problem in Cavaliers, and is DEFINATELY (sp) something to consider.
As I said earlier, I'd have a cavalier right now if it wasn't for MVD. After research, the right breed for us was a cockapoo (cocker spaniel/poodle, once again, don't be surprised if this sounds just a bit biased
). They have few health problems, are low shedders (good for allergy sufferers, which was good because my mother is mildly alllergic to dogs), love to swim, are small (if from mini or toy poodles), and are real people-dogs. They do have a coat that grows all of the time, though, so it will need occasional clipping. Even though it is a "designer dog", if it fits your lifestyle, then go for it. I know alot of people here don't like the idea of mixed breeds from a breeder, but remember, it's your decision, not theirs. That's what I thought about, and soon I'll have the breed that I've discovered is right for me after 2 years of research. Anyway, a cockapoo might be a good idea for you.
But remember, puppies need UNLIMITED patience, especially with housebreaking. They also need to be trained, and if not socialized properly, even the best breed for someone can turn out to be an aggressive, shy, and snappy dog. If you not ready for the commitment, then go to a shelter or a rescue, beause that is undoubtably the best choice for someone who can't handle the time a puppy requires for more than a year. The good thing about rescue dogs are that you know what you are getting. You know if he is dominant, or shy, or right in between. You know if he is a people-dog or is fairly independent. You know how big he is, what his activity level is, and whether he is good with other animals or not. In your situation, I would reccomend an adult dog from a shelter or rescue. Petfinder.com is the best website for people looking to adopt a dog, I even look on it daily now just for fun.
